Simplified Single Phase Thyristor / SCR / Compact Power Controller

The Eurotherm EPack Lite-1PH Compact SCR Power Controller delivers essential, single-phase power control expertise in a compact format, built for end users, machine builders and system integrators who need the best combination of performance, ease of use and reliability to control the energy delivered to their process. EPack Lite-1PH offers a simplified feature set for fast commissioning without compromising on performance, controlling single phase non-variable resistive, primary transformer and short wave infrared loads. Configurable firing modes allow close matching to load characteristics to optimize process efficiency.

Key Features

• Wide voltage range — A large voltage capability from 100V to 500V, adjustable within the same variant.
• Fast start up — 'Quick Start' or 'Clone Code' features get the unit commissioned quickly.
• Adjustable control mode — V², I² or open loop control to suit the application.
• Wide range of firing modes — Phase angle, intelligent half cycle, variable modulation burst firing, fixed modulation period and logic mode.
• Built-in measurements — Current, voltage, impedance and more, without added hardware.
• Load fault detection — Detects a fault down to 1 element of 6.
• SCCR 100kA with fuse — Rated conditional short-circuit current of 100kA (coordination type 1) for robust protection.

Benefits

Helps maximize yield with accurate and repeatable control, and delivers fast integration and commissioning thanks to the built-in user display. Ease of operation and maintenance, combined with a simplified design, reduces stock and spares holding for OEMs, system integrators and end users alike.

Specifications

The EPack Lite-1PH covers a nominal current range of 4 to 125 amps, with a nominal voltage from 100V to 500V (+10%/-15%) and accuracy of ±2% of full scale, operating at 47Hz to 63Hz. Short circuit protection is provided by external supplemental high speed fuses, and the unit supports firing modes including phase angle, intelligent half cycle, variable modulation burst firing, fixed modulation period and logic mode, with control modes of V² control, I² control, and open loop with feedforward and trim modes. The unit features a 1.4 in. diagonal TFT display for configuration, monitoring and diagnostics. Operating temperature range is 0 to 45°C at 1000m (32°F to 113°F at 3280 feet), derating to 0 to 40°C at 2000m (32°F to 104°F at 6562 feet), with a storage temperature of -25°C to 70°C (-13°F to 158°F).

Available Models

The EPack Lite-1PH Compact SCR Power Controller is available across the following current ratings, each fitting one of four common mechanical footprints.

16 to 32A models (129.2 x 51 x 136.2mm, 0.8kg): EPack Lite-1PH 16A EPack Lite-1PH 25A EPack Lite-1PH 32A

40 to 63A models (129.2 x 72 x 173.3mm, 0.95kg): EPack Lite-1PH 40A EPack Lite-1PH 50A EPack Lite-1PH 63A

80 to 100A models (197.6 x 80 x 202.1mm, 1.8kg): EPack Lite-1PH 80A EPack Lite-1PH 100A

125A model (197.6 x 120 x 202.1mm, 2.5kg): EPack Lite-1PH 125A

Each model is built to order using Eurotherm's EPack Lite-1PH order code, which lets you specify auxiliary power supply, control option (V², I², or open loop), warranty, fuse type, nominal load current and line voltage, load and heater type, firing mode, and analog and digital input configuration. Existing units can also have their current rating upgraded in the field using a software key order code.
